How do Christians look to others?

I recently went to a seminar and was able to be helpful to the presenter. He asked me what I do and I told him that I’m a pastor and software developer. Then he sighed and said, “Why do the kind and helpful people always turn out to be Christians?”

I don’t think ALL the kind and helpful people are Christians, but it’s a job requirement for followers of Jesus, right?
